| 摘 要： | 通过有限元计算和试验,探讨了垫条宽度对混凝土劈裂抗拉试验的影响.结果表明:当垫条宽度与立方体试件边长的比值k在0.167～0.600时,有效缓解了加载部位的应力集中,能保证立方体试件在端面中心处起裂.

| Abstract: | The effect of spacer width on concrete split tests is discussed through finite element calculation and tests.The results show that when the ratio of spacer width to side length of cube specimen k is within 0.167~0.600,the stress concentration in load area can be effectively mitigated,then the crack initiation from the center section of end face of the cubic specimen can be ensured. |
